before nic was working fine, suddenly problem came, network was working but when try to see properties of network connection of Lan, It was not working, even name of NIC was not coming in LAN connection properties, however network was working fine. In order to fix, we removed NIC driver but after that now it is not configuring NIC and message is coming
#E154 Class installer failed. Error 2: The system cannot find the file specified. in setup.api.log.
i tried to install microsoft loopback adapter. it was also not working.
